Platinum(II) diimine complexes with naphthalimide substituted fluorenylacetylide ligands are synthesized and characterized. The complexes exhibit long-lived 3ILCT or 3ILCT/3MLCT/3LLCT excited states (τ = ∼20–30 μs) and broadband triplet transient absorption in the visible-NIR region. Nonlinear transmission experiments at 532 nm demonstrate that these complexes are efficient nonlinear absorbing materials
合成并表征了具有萘二甲酰亚胺取代的芴基乙炔配体的铂(Ⅱ)二亚胺配合物。这些复合物在可见光-NIR区域表现出长寿命的3 ILCT或3 ILCT / 3 MLCT / 3 LLCT激发态(τ =约20–30μs)和宽带三重态瞬态吸收。532 nm的非线性透射实验表明,这些络合物是有效的非线性吸收材料。
